What is the standard size of a dishwasher?

• <div><p>A standard <a href="https://www.angi.com/articles/dishwasher-sizes.htm">dishwasher size</a> is 24-by-24-by-35-inch for a built-in unit. The depth and height line up perfectly with most kitchen countertops and cabinet sizes. </p></div>

How long will it take to install my dishwasher?

• <div><p>Installing a dishwasher should take one to four hours, depending on the complexity of the installation and whether you DIY or hire a pro. Even if you're particularly handy, installing a dishwasher on your own will likely take longer — at least two hours. On the other hand, a professional can likely install a dishwasher in about an hour. Installation time will take longer if you have to remove an existing dishwasher, reroute plumbing, or repair damaged flooring underneath the appliance.</p></div>

Can you clean a moldy dishwasher with bleach?

• <div><p>Your first instinct might be to grab the bleach to clean a moldy dishwasher, but it’s not the best product for the job. You don’t want to use bleach to <a href="https://www.angi.com/articles/how-clean-stainless-steel.htm">clean stainless steel</a> components if your dishwasher has them, as it can cause significant damage. In addition, the scent of bleach can linger if not rinsed well, causing your dishes to retain a smell (and even taste) of bleach.</p></div>

Why does a dishwasher have to drain through the sink plumbing?

• <div><p>Any drain in your house requires a water trap to prevent sewer gases from entering the home. Dishwashers don’t have an internal water trap, so they must use an external P trap. The most convenient P trap for the dishwasher is already in the plumbing under your sink.</p></div>

Dishwasher Installation FAQs, answered by experts

A standard dishwasher size is 24-by-24-by-35-inch for a built-in unit. The depth and height line up perfectly with most kitchen countertops and cabinet sizes.

Installing a dishwasher should take one to four hours, depending on the complexity of the installation and whether you DIY or hire a pro. Even if you're particularly handy, installing a dishwasher on your own will likely take longer — at least two hours. On the other hand, a professional can likely install a dishwasher in about an hour. Installation time will take longer if you have to remove an existing dishwasher, reroute plumbing, or repair damaged flooring underneath the appliance.

Your first instinct might be to grab the bleach to clean a moldy dishwasher, but it’s not the best product for the job. You don’t want to use bleach to clean stainless steel components if your dishwasher has them, as it can cause significant damage. In addition, the scent of bleach can linger if not rinsed well, causing your dishes to retain a smell (and even taste) of bleach.

Any drain in your house requires a water trap to prevent sewer gases from entering the home. Dishwashers don’t have an internal water trap, so they must use an external P trap. The most convenient P trap for the dishwasher is already in the plumbing under your sink.

The frequency for cleaning your dishwasher filter depends on your usage habits. If you run the dishwasher daily and don't scrape or rinse dishes before loading, you should clean the filter about once a month. For those who use it only once or twice a week and rinse items beforehand, cleaning it every three to six months may be sufficient. A clear sign that your filter needs cleaning is a musty smell, even after a wash cycle. Regularly cleaning the filter is important to prevent food buildup and clogging over time. It can be helpful to add this maintenance task to your calendar to stay on schedule.
